10,000 lux on 2 week olds. Too much light? Damage?

My last batch of 5 autos (all different strains) I started the seeds at 25-30k lux, and it caused no issues. This was in Coco/perlite, Canna Coco a/b, 18/6 light, 50-60% RH, 28-32C. By 2 weeks they were on 45k lux. At no time was there bleaching or light stress. Light distance is 60cm. Water is tap water @ 400ppm (120ppm calcium/magnesium , no cal/mag added) + a/b @ 40ml/10L, pH to 5.5-6.0. I'm breaking a few people's rules here, but some things just needed to be tested as a seed in nature doesn't always start out in the shade.

Lights used were 3500k + 660nm lm301b. Lux levels were measured with a meter calibrated for 6500k. I'm at 3 weeks now and they are still powering on like crazy. I've had a few days of 32C in the tent that have caused minor taco but they recover pretty quickly. The oscillating fan is on 24/7, and the exhaust fan runs when the temp exceeds 28C, which is a good portion of daylight hours.
